Description

RESOURCES REMAKE METHOD AND EQUIPMENT CONSTRUCTION}

The present invention relates to a method and apparatus for recycling resources of construction waste.

In general, recycling means that the use of recyclable resources is technically and economically feasible, and for the efficient use of such resources.In particular, in the case of waste cones, waste ascons, waste wood, rebars, earth and sand, and other redevelopment sites, Types of cases that cannot be separated due to working conditions The amount of domestic construction waste and construction waste such as construction waste, waste vinyl and household waste reaches 40 million tons per year, but more than 90% is filled. Recycling performance in high value-added areas that are only used for landfilling is very poor.

Therefore, the method and apparatus for efficiently sorting and recycling them reveal that there are already technical means that can be processed in Korea.

All conventional sorting machines are sorted in the same way as the same system, although there will be qualitative differences in the types of waste.

That is, in the conventional sorting method, when the mixed waste is put into the hopper, the belt conveyor transfers it to the trommel (hereinafter referred to as the sorting box) inlet and then rotates through the sorting net, that is, the net, which is passed through the net, earth and sand, etc. Is transported to a transfer device located at the bottom of the sorting container and sorted by another method, and combustible waste, wood, and large chunks of waste corn particles which have not passed through the screen of the sorting container are transported by a belt conveyor installed at the sorting outlet. The material having a small specific gravity is scattered by the wind power of the blower installed at the drop position of the end of the belt conveyor, and the material having the large specific gravity is landfilled after being transported by natural dropping or belt conveyor.

However, in the conventional sorting device, the waste with high wet moisture content increases the cause of the absolute reduction of the sorting efficiency and the high energy consumption due to the clogging of the sorting container.

Therefore, it is widely used as a solution to install the impact device using the metal butch tool, but this causes a secondary problem due to noise amplification, there is a problem that causes the breakage of the network, and rotates to another method This material clogging in the screen of the sorting box is burned by burning the flames of the burner and burned, and the vinyl attached to the screen is burned and then blown with high-pressure air to increase the separation and sorting, but this is caused by the overheating of the burner over 1000 ℃. There was no problem of producing fatal secondary pollution due to direct incineration.

In addition, the waste containing the wet has a problem of oxidizing the sorting box made of a metallic material, and the light and heavy aggregates are directly put into the sorting box to cause amplification of noise and breakage of the sorting box when the sorting box is rotated.

And the aggregates sorted by the discharge port in the sorting box are sorted by the blower installed at the end of the belt conveyor to sort out the small specific materials and the large specific materials.

The waste forms a thick layer at the end of the belt conveyor, and when the belt conveyor falls, high-concentration materials such as waste cones and combustible materials such as paper, cloth, and vinyl are interconverted, which reduces the sorting efficiency of combustible waste. The selected combustible material is incinerated in a situation where it is adsorbed on many soils.

This secondaryly increased the transportation costs, caused a lot of heat energy consumption during incineration, and caused a significant problem in the treatment cost for the residue after incineration.

The present invention has been made to solve the above problems, for the purpose of setting the primary screening unit installed inclined U-shaped buchesal screen and inclined belt conveyor between the hopper and the sorting bin to which the mixed waste is introduced In order to separate all the light and heavy wastes from the primary screening unit, only the combustible material, the earth and sand, and a small amount of light aggregates are entered into the sorting box so that the organic soils available for agriculture can be sorted. If it does not enter, all wastes such as waste cones of heavy weight are separated from primary shredding → primary electromagnet scrap separation → earth quarry separation → combustible waste sorting tank → raw stone-foreign material separation → raw stone-washing → secondary fracturing → secondary electromagnet scrap It is to provide high quality recycled aggregate through intermediate treatment facilities such as separation → multi-stage product separation → third electromagnet-iron strip separation process. Will that purpose.

Means capable of separating the mixed light, heavy waste of the present invention in the primary screening unit for achieving the above object;

The upper side of the inclined bottom plate 22 of the hopper 21 disposed at the primary opening 20 of the main body 10 is formed of a sealing plate 22a having a wear-resistant reinforcing plate, and the lower side thereof is a U-shaped buccal screen 22b. When the waste material such as waste cone of heavy weight is introduced into the hopper 21 and sorted by the moving size to the screen 22b, the sorted waste falls to the collector 23 disposed below the screen 22b. , The waste not sorted on the screen 22b is dropped from the end of the belt conveyor 25 inclined between the hopper 21 and the sorting tube 24, and the waste cone mass having a large gravity center is gravity-induced by inertial force. While falling by to be guided to the collector 23 to form a primary screening unit 20.

As a means for inducing the wet combustible waste ie waste vinyl, household garbage, earth and sand, lightweight aggregate, etc. into the sorting bin 24;

The upper part of the primary screening part 20 is formed with the guide plate 26, and the hot air fan 27 which has the exhaust pipe 27 'is arrange | positioned behind the U-shaped screen 22b, and is through the exhaust pipe 27'. The generated hot hot air dries the wet waste that is sorted or transferred to the U-shaped chatsal screen 22b, and at the same time, the hot hot wind passing between the plurality of screens 22b formed into equal portions is the waste falling from the hopper 21. Soil and light weight aggregate scattered in contact with the guide is guided to the guide plate 26, the guide plate 26 is guided to the screening cylinder 24 so that combustible waste can enter the screening cylinder (24).

Means that can be selected in the primary screening unit 20 in the case of dry waste that does not contain water;

The sealing plate 22c disposed on the sealing plate 22a in a stack is slid downward to close the U-shaped buccal screen 22b, to stop the operation of the hot air blower 27, and the belt conveyor 25 using gravity. In operation only, the dry waste introduced into the hopper 21 is dropped into the belt conveyor 25 at the end of transfer to the sealing plates 22a and 22c, and the light and heavy waste aggregates are collected by the gravity collector 23. Collected and separated into an intermediate treatment facility, and scattered soil or some lightweight aggregate was allowed to enter the sorting bin (24).

The process of producing high quality aggregate by the intermediate treatment facility of light and heavy waste separated by the primary sorting unit 20 is as follows.

A primary shredding process of shredding the waste cones gravitationally selected by the inertia force such as a large waste cone mass below 200mm

A primary electromagnet delamination process for sorting flakes contained in waste crushed to less than 200 mm,

In the process of earth and sand separation process to sort the remaining soil and aggregates, transfer the waste crushed to less than 200mm to the horizontal screen less than 25mm in diameter,

Winter season, rainy season ↔ summer season, and dry season, the process can be different,

First of all, winter season and rainwater season have been organized in consideration of freezing and wetting. Water is not available.

In other words, the soil and aggregates are sorted on the horizontal screen, and the selected soil is collected and processed at a certain place through the transfer device, and the aggregate and the flammable waste are scattered and separated by the wind power of the blower installed under the horizontal screen. It is separated into the discharge part of the tank, and the aggregate (more than 25mm) is transferred to the buccal-type multi-stage screen and moved to the winding washing by the conveying device.

In the summer and the dry season, there is no wet and freezing, so water can be used. It is the same to sort the remaining soil and aggregate by transferring it to a horizontal screen of 25 mm or less. The existing wastes are sedimented, and flammable wastes are separated and sorted out.

Inside the combustible sorting tank, it is the facility where high pressure aeration generates impurities and high-pressure washing of aggregates, and the water spray high pressure nozzle that can adjust the water flow in the direction of the next chat buccal bucket screen and the float in the combustible sorting tank The chat chat bucket will be sent to the screen.

Secondary crushing process that can separate 25mm or more and 200mm aggregates from the sedimentary stone separation process to 100mm or less of the secondary washing screen,

High-quality recycled aggregate by installing 3rd electromagnet iron separation process in the discharge conveying device of 25mm or more in the three-stage screen net process that can be selected according to the desired size such as 9mm, 15mm, 40mm among the aggregates below 25mm to 100mm after the secondary strip separation process Is produced,

Aggregates not sorted in the three-stage screen net process are recycled back to the cone crusher or impact crusher, but the upper part of the transfer device is separated through the fourth electromagnet iron strip separation process, and then sorted again by the three-stage screen net. It is a process that can be reproduced.

Meanwhile, the waste separated in the primary sorting unit 20 and brought into the sorting container 24 may be classified into dry and moisture-containing waste.

In the case of first treating the waste containing moisture as a means for drying the waste in a sufficient time to increase the work efficiency;

The chain 29 is coupled to the sprocket 28 formed on the outer circumferential surface of the front end of the sorting cylinder 24, and the chain 29 is constructed on the shaft of the reduction motor M operated by the variable transmission,

The deceleration motor (M) sets the driving speed by freely selecting the high speed and the low speed, and in this case, the waste water containing moisture is converted into a low speed, and compressed air, that is, pressure energy, is placed above the sorting cylinder 24. A plurality of high-pressure exhaust pipes (30) having a hot air at the same time by converting them into high-speed energy is disposed, and the sorting tube (24) is arranged in parallel with a plurality of rods (24 ') of diameter 16mm in the upper network ( 24a), the lower net 24a is coupled to the lower net 24b, and the upper and lower nets 24a and 24b are simultaneously formed in a circular shape by a bending device, and the upper and lower nets 24a are formed. 24b is made of stainless steel (SUS),

When water-containing waste flows into the sorting container 24, the deceleration motor M, which is a power source, is driven at a low speed, and the high pressure exhaust pipe 30 injects air at hot wind and high speed and reciprocates at the same time. The waste which tries to contact the sorting container 24 by moisture is dried and moves to the sorting container 24 exit without being touched.

In addition, as the processing means of the earth and sand to be treated in the sorting tube (24);

Below the sorting container 24, there is a belt conveyor 31 which can transfer the soil which passed through the sorting container 24 to one place, and this belt conveyor 31 connects the soil to the appropriate position of a yard. To be gathered in one place.

Means for treating combustible waste and some lightweight aggregates that are not sorted within the sorting bin 24 and are treated at the ends of the sorting bin 24;

The blower 32 disposed at the end of the sorting tube 24 is introduced into the duct 33 by flying the combustible waste falling from the sorting tube 24 into the wind, where the combustible material scattered is introduced into the inlet of the duct 33. Shattering curtains 34 are disposed at the ends of the sorting tube 24 to guide the combustible wastes that have passed through the ducts 33 to be collected at a yard.

The lightweight aggregate falling from the end of the sorting tube 24 without being scattered by the wind flows into the belt conveyor 35 disposed under the duct 33, and the introduced aggregate moves to the belt conveyor 35. In the electromagnet 36 that can separate the steel contained in the aggregate is disposed on the belt conveyor (35) to separate the steel, the aggregate is separated from the steel aggregate to be placed in a yard constant place.

As a means at the time of processing the dry waste put into the sorting container 24;

As described above in the primary sorting unit 20, the operation of the hot air blower 27 is stopped, and only the belt conveyor 25 using gravity of the waste is operated. The dry waste introduced into the hopper 21 is sealed plate 22a. (22c) at the end of the transfer to the belt conveyor (25) by the falling gravity, light and heavy waste aggregates are collected in the collector 23, the remaining combustible material, earth and sand, some lightweight aggregates are transferred to the intermediate treatment facility is a sorting container ( Go to 24). At this time, the dry waste is to increase the smooth working efficiency even if the waste containing the water rotates the sorting bin (24) at high speed.

That is, since the deceleration motor (M) for driving the sorting cylinder (24) operates using a variable transmission, it is possible to freely adjust the high speed and the low speed, and another feature of the deceleration motor (M) is a process in which the sorting cylinder (24) operates. In the case of power off or accidents in human life, when the excessive amount is put in the sorting container 24, when it is operated again, it has the advantage of being able to bear the overload.

Means that can easily check the inside of the sorting tube 24 during the breakdown or maintenance of the sorting tube 24 for a certain period of time;

On both sides of the sorting tube 24, the opening piece 37 opened by the many hinge 37 'was arrange | positioned.

As a means for compensating for effective power transmission when the chain 29 loosening with the sprocket 28 formed on the outer circumferential surface at the tip of the sorting tube 24 is loosened;

The chain tension piece 41 provided on the roller frame 40 is provided, and the chain 29 is placed on this chain tension piece 41.

Another embodiment of the sorting bin 24 is to be attached to the sorting bin having a 150 mesh when the soil, waste cones, etc. of the waste carried into the sorting bin 24 forms the mainstream,

The fastening holes 42 drilled on the outer circumferential surface of the sorting cylinder 24 and the fastening holes 240 'of the detachable sorting cylinder 240 were matched to each other to be fastened by the fastening bolts 43.

Referring to the embodiment of the present invention configured as described above are as follows.

First, when light and heavy wastes mixed in the hopper 21 disposed in the primary sorting unit 20 are dropped into the sealing plate 22a of the bottom plate 22 of the hopper 21, the sealing plate (22a) is made of abrasion-resistant reinforcing plate, which does not cause breakage or deformation even if a large gravity waste falls.

The waste dropped on the sealing plate 22a is moved to the next U-shaped but chatsal screen 22b, in which the waste passed between each equal portion of the screen 22b falls to the collector 23 disposed below it. do. At this time, the fine soil is scattered by the wind exhausted from the exhaust pipe 27 'of the hot air blower 27 and is transferred to the induction plate 26, and a part of the waste containing moisture due to high temperature hot air is dried at a predetermined time. Falling to the furnace collector 23, some will be scattered to the guide plate 26.

On the other hand, the large specific waste sorted by the screen 22b is collected in the collector 23 by the falling gravity at the lower end of the belt conveyor 25.

Aggregate collected in the collector 23 of the primary sorting unit 20 is divided into primary crushing process → primary electromagnet iron separation process → soil stone separation process → flammable waste sorting and erection → raw material-sediment separation → raw material-washing → secondary High quality recycled aggregate is produced by shredding process → Secondary electromagnet scrap separation process → 3 step screen net process, and more than 25mm is transferred to 3rd electromagnet iron piece separation process disposed at the upper end of the transfer device, and the 3 screen net Aggregate not screened in the process is recycled back to the cone or impact crusher, but at this time, the transfer device is separated through the 4th electromagnet iron piece fixing and the final iron piece is separated and the remaining aggregates are crushed. It is a process that can be reproduced by.

Meanwhile, the waste separated in the primary sorting unit 20 and brought into the sorting container 24 may be classified into dry and moisture-containing waste.

First of all, when treating waste containing moisture, the waste carried in the sorting container 24 is dried at a sufficient time to increase the efficiency of sorting. When the reduction motor (M) having a variable transmission is converted to low speed, The sprocket 28 engaged with the chain 29 arranged on the reduction motor M shaft is driven to rotate the sorting tube 24 at a low speed.

In addition, in the upper part of the sorting cylinder 24, waste gas, which converts compressed air, that is, pressure energy, into velocity energy and injects it at a high speed, and at the same time has a high pressure exhaust pipe 30 having hot air, reciprocates left and right to contact the sorting cylinder 24. Does not touch and moves to the sorting tube 24 exit. At this time, the earth and sand that passed through the screen of the sorting container 24 is dropped to the belt kenveyer 31 disposed below the sorting container 24, and the belt conveyor 31 is to be gathered at an appropriate position of the yard.

In addition, the combustible waste and some lightweight aggregates that are not sorted in the sorting tube 24 and processed at the end of the sorting tube 24 are combustible waste by the wind power of the blower 32 disposed at the end of the sorting tube 24. Some soil and dust that is scattered inflow into the duct 33, the waste introduced into the duct 33 is to be collected in a certain place of the yard, and also scattered in the wind of the blower 32 at the end of the sorting tube 24.
